Recently I pulled a project form Github. The language I'm working with is C. When I try to run it, it will say "The selection cannot be launched, and there are no recent launches." I can't compile either. So what I did was search the internet for how to fix this. And the mighty internet said I shall change my run configurations and select my project and then run that. This is what I tried - I opened the configurator and browsed for my project, but it wasn't displayed. I can see the project in the navigator and I can commit/push/pull as well. Still, I can't choose it in the run configurator. Any ideas what I could do?
Thank you very much!
PS: I already saw this post (Can't run project in Eclipse imported from Git) but there is no maven option when importing.

I had made an maven project and it worked fine.
Then I installed plugins
EclEmma Java Code Coverage,
PHP Development Tools (PDT),
Eclipse.orgSonarQube
Then I worked on some other project. When I again wanted to create an maven project,it threw the following error window which said
The selected wizard could not be started
reason
plug-in org.eclipse.m2e.core.ui was unable to load class
org.eclipse.m2e.core.ui.internal wizards.MavenProjectWizard
Removed SonarQube plugin .This solved the issue.
Now it works all fine.
But is there any other solution to this problem since I have to use sonar.
Click on eclipse help tab and open installation details search sonar and remove all related plugins.
That's not quite the right characterization of what it says on the page,Please check your .log file /path/workspace/.metadata/
Find the correct plugin which is causing this problem and update to compatible version of the plugin with eclipse version.
To find the hidden files in the workspace use Ctrl+H
I had the same problem, and I've tried so many solutions. But what I did to solve the problem, is that I just upgraded my Eclipse IDE (2019-06 to 2020-03) by following these steps (from https://wiki.eclipse.org/FAQ_How_do_I_upgrade_Eclipse_IDE%3F) :
You first need to add the new release's repository as follows:
1-1. Window > Preferences > Install/Update > Available Software Sites
1-2. Click 'Add'
1-3. Enter the URL https://download.eclipse.org/releases/2020-03/
1-4. Click 'Ok'
Help > Check for Updates
If updates are found, proceed through the install wizard and restart the IDE when
prompted. Otherwise, read carefully the error message to find out which component
is conflicting and establish your resolution strategy.
Note that the start splash screen may be cached and will not necessarily be
updated to the latest version after the IDE is restarted. Performing a full
relaunch should display the new version number.
After months of using Eclipse (latest Kepler release) on Ubuntu (13.10), after rebooting from to a sudden loss of power on my laptop, now Eclipse won't let me access java classes within their packages. It simply just shows the packages names but when I click on these the java classes are not showing.
Please note that even though I have several Maven projects working, this happens only on one specific project.
Steps so far:
1) I checked the permissions of all the java files and the directories.
2) Tried updating the project but no luck, also reverted back to my an earlier version (SVN) but didn't help either.
3) I tried deleting .eclipse and re-installing Eclipse and importing my projects, but unfortunately it didn't resolve the issue.
4) I have checked the .classpath file which seems ok.
5) Recursively 'touch' all the files, but still nothing.
I believe that this is a Maven + Eclipse related issue but I have ran out of options here, so I am open to suggestions. Thanks...
Probably it is not a problem of the project but of the workspace metadata. Please create a new workspace and important the project there. Are you able to browser the package explorer there?
Those are empty packages as you know. we need to right click on those packages and create class then you would probably see classes.
In case u still can't see classes then Go to Window->show view->Package explorer
you will be able to see packages along with classes tagged. if you have created any.

Okay I am starting to give up with this. I have been trying to setup sebversion in Eclipse for my android project. I have been following the following tutorial
http://blog.bauson.com/eclipse-subclipse-svn-hostgator-com.html
I got the following:
Created a repository called myRep
Created a project under with source files myRep/TestProject and attached it to trunk
installed subclipse and got it to grab the repository
Now when, it says "Checkout as a project configured using the new project wizard", I get to choose the type of project. If I choose android application project then it creates a default android project and nothing is checked out. But when I choose General Project, it does grab the whole thing in the following structure
Repositony->TestProject->Trunk->All my android files and folders
However I want it to be android project so I can compile and run it. I did a lot of googling and I need your help pleeease!
Never mind, I figured it out. Apperently, when you choose the repository you have to right click and click refresh and it will show you a list of Folders (stupid eclipse does not do it automatically). Then you choose your project and create it as a new project. Voilla, you get it compiling and running
I have the source code for the VersionOne plugin. I am wanting to modify the code because I am getting a NullPointerException when I click a specific button on the plugin which crashes eclipse. I was wondering what steps I need to take in eclipse to import the source code, modify it, and get it to run. I have read over how to create a new plugin project, but I have never tried importing a plugin before. Plugin Source
Once you have imported the project and that seems to work fine, just run it like any other plugin.
I.e:
Set the breakpoints you want in the code
Click the "Run as..."
In the run dialog start up a new Eclipse instance
On the tab "plugins" make sure your imported plugin is selected
If you are using the plugin at the same time, make sure that the non-workspace is not selected
In the new Eclipse instance, set up a situation that will provoke the bug
You need the following things to do that:
From Eclipse download a distro with PDE (Plugin Development) included.
The source pages
Some configuration management tool like Git or Subversion.
You do then the following steps:
Unzip your sources locally somewhere and add them to the CM system.
Create an eclipse plugin project from that source location (depending on Git or SVN different steps).
Create a run configuration for Eclipse that includes that plugin. That is similar to creating a run configuration for Java, but your Java application is then eclipse (see the Help on Eclipse Application Launcher). You have to ensure that in the "Plug-ins Tab", your new plugin is included. After you have started it, you should see the new feature implemented in the new running eclipse. To debug it, you just have to press the debug button instead of the run button. You may then add breakpoints to the source code of your plugin to see how it is working.
You are then able to start a new eclipse application which includes the plugin and make your tests there. You are able to set breakpoints, debug the code and so on. If you find the error, you can change the code, test it, and as a result have a difference to the source you had initially. The best would be then to make a patch and send it back to the originator.
To deploy it then to others is a different story, and is well documented.
On my Mac computer, I follow the tutorial on this page to get the Taipan example run, but still failed so many times.
Switch to the Plug-in Development perspective and open the models folder within the org.eclipse.gmf.examples.taipan project. Explore each of the models found hereand their element properties. You'll notice that there are full and RCP versions of the generated Taipan examples to explore.
When I try to run as "Eclipse application", it launches a new eclipse app but the dialog box Examples does not have the 'Taipan Diagram' as it says:
create an empty project and a new 'TaiPan Diagram' found in the Examples folder of the New dialog
What are the possible causes? Someone helps me to solve it out?
I'm assuming that your plugin is working fine and doesnt show compilation errors?
Then the most likely reason is that you havent chosen your plugin to be active in your launch dialog.
I answered a similar question with this:
My guess is that you have just created the plugin, but aren't running it in your current Eclipse instance. That can be verified by opening the view "Plugin registry". That will show a list of all plugins, see if the plugin you have created is in that list.
If you click on the run button in Eclipse you will open a run configuration dialog. In one of the tabs, you get to choose what plugins should be available. Make sure your plug-in is selected. This will start up a new Eclipse instance that will run your plugin.
To make your plugin be a part of your ordinary Eclipse installation, you will need to export it to a jar and copy that jar to the dropins catalog.
